Built between 527 and 565 AD at the foot of Mount Sinai for Emperor Justinian, this monastery later took its name from St Catherine of Alexandria, whose remains are said to rest here. It’s more fortress than church, with thick stone walls guarding the Church of the Transfiguration, the chapel of the Burning Bush, and a monks-only library packed with ancient manuscripts. Inside, you’ll find mosaics, religious ornaments, and some of the oldest illuminated manuscripts in the world on display. Outside, don’t miss Moses’ Well and the garden with centuries of history. The place is open most mornings but closed on Fridays, Sundays, and Orthodox feast days. Still active today, the monastery holds importance across Christianity, Judaism, and Islam, and continues its Greek Orthodox traditions uninterrupted.

Perched on the rocky edge of Mallorca, Castell d'Alaro is one of the island's most rewarding climbs, recommended by lovers of both history and nature. These ruins are a crumbling castle, several arched stone doors, and wall remnants are all that remains of what was once the fortress of 9th-century Christian warriors. If you're less adventurous, you may drive to the ascent to take in the stunning views over almost the entire island. In case you want to stay overnight, Castell d'Alaró also functions as a guesthouse. There's also a small bar and restaurant where you can recharge your batteries and enjoy a meal with fantastic views.

Oviedo’s Cathedral combines Gothic, Baroque and Renaissance elements. Its 15th-century spire looms over a medieval basilica built by the first prince of Asturias.

The cloister is home to the Diocesan Museum, with a number of important archaeological relics.
